NOTE 1: Canon 10D, 20D, 5D Mk I, 1D/1Ds MkI and 1D/1Ds MkII cameras are not supported by the Promote Control HDR mode (with or without CN3 cable). Only a limited subset of basic features such as One-Shot, Time Lapse and Manual Hold are possible on these cameras, and would require a CN3 cable to be connected.

NOTE 2: Canon 5D Mk III and 6D cannot be automatically switched to Bulb mode if/when required by HDR bracketing (>30 second exposures only). A prompt will be shown on the Promote Control screen if a Bulb mode is required in HDR mode.

All other cameras mentioned above are fully compatible, including HDR mode.
